Quecksilber Erfassung von Immissionswirkungen Biomonitoring mit der Standardisierten Graskultur: Eignungstest

An approach to biomonitoring of immission-induced mercury contents (= immission effects) in standardized grass cultures was made at locations with different settlement structures and in the vicinity of two waste incineration plants in the context of a research project dealing with “Active biomonitoring of immission effects in the testing area of Munich”. In 1992, mercury could be found in most grass samples using the method of cold vapor atomic absorption spectrometry (CVAAS) with an analytical detection limit of 20 µg/kg dry mass. With a new detection limit of 5 µg/kg dry mass attained by a better analytical procedure, mercury could be detected in all grass samples of 1993. An influence of the two examined waste incineration plants on the mercury content in grass could not be detected, although a relationship between mercury contents in the standardized grass culture and settlement structures is indicated.
